Application filed August 27, 1907.

T 0 all whom it may concern:

Be it known that I, WILLIAM W. ADDING- TON, a citizen of the United States of America, residing at Inde endence, in the county of Montgomery and tate of Kansas, have in-.

vented new and useful Improvements in Railway-Switches, of which the following is a specification.

This invention is an improved train-operated railway switch in which the movable switch points are actuated by devices with which the trains are employed and which are controlled by the engineers, as hereinafter described and claimed.

One object of this invention is to provide improved means for actuating the movable switch oints.

Anot er object is to provide improved train-carried tappet devices for operating the devices which actuate the switch points.

Another object is to combine with the train-operated switch point moving devices automatically operated signal devices to indicate the position of the switches.

A further object is to provide improved means for locking the switch points when set and preventing casual movement thereof.

In the accompanying drawings,-Figure 1 is a top plan view of a portion of a railway track and of the side track provided with my improved train-operated devices for actuating the switch points and setting the signals. Fig. 2 is a detail perspective view of the train-operated toggle bars which actuate the switch points. Fig. 3 is a diagrammatic perspective view showing the connections etween such train actuated toggle bars. Fig. 4 is a vertical transverse sectional view of the switch showing the devices for auto matically locking the switch points when set. Fig. 5 is an elevation of a locomotive truck provided with my improved train-carried devices for actuating the toggle bars. Fig. 6 is a side elevation of the same.

The movable switch points 1, 2 are connected together by a bar 3 which is movable therewith and which has its ends secured under the bases thereof, the extreme ends 4 of said bar being upturned to bear on the outer sides of the switch points and plates 5 being bolted on the said bar and engaging the inner base flanges of the switch points, as shown in detail in Fig. 1. The said connecting bar is provided at or near its center with a pair of depending guide and stop lugs 6, through the openings in which extends a longitudinally Specification of Letters Patent.

of the track rails 12.

movable operating rod 7 which is provided with a stop collar 8 that operates between the said lugs. A pair of spring catches 9 have their inner ends secured, as at 10, to the underside of the bar 3 near the ends thereof and have their outer ends upturned, as at 11, to engage the outer sides of the base flanges The said catches spring upwardly to lie flat against the underside of the bar 3 and engage the said track rails. A pair of catch-operating levers 13 are carried by and fulcrumed to the bar 3, as at 14, each of the said levers having an arm 15 to bear on and depress one of the catches or locking devices 9 and also having a depending arm 16. The rod 7 is attached to the said depending arms of the said levers to turn said levers simultaneously when the said rod is moved in either direction and cause one of said levers to depress one of the catches or locks 9 to release the same from one of the track rails and enable the other catch or lock to move upwardly so as to engage the opposite track rail and thereby lock the bar 3 in the new position assumed thereby, and hence lock the switch points in the position to which they were set by the action of the said rod 7, it being understood that the stops 6, 8 with which the rod 7 and bar 3 are respectively provided adapt the said rod to move longitudinally to some extent indepcndently of said bar and cause said bar to thereafter move with said rod. The said rod 7 is connected at one end to a semaphore or other indicating or signaling device here shown at 17 in Fig. 1. The said rod is also attached to a bell crank 18. Hence said bell crank and the signaling device which inclicates the position of the switch points are movable simultaneously with such switch points.

At suitable distances from the switch at opposite sides of the same are pairs of vertically movable train operated toggle bars 19, 20. The members of the said pairs of toggle bars are pivotally connected together at their inner ends, as at 21, and. the outer end of one member of each bar is slotted longitudinally, as at 22, to receive a spike or the like device to pivotally secure the same to a cross tie, the free ends of the other toggle bars operating on other cross ties or other suitable supports. The pivotally jointed portions of the said toggle bars are thus adapted to be moved vertically, as will be understood. One member of each pair of the toggle bars is provided with a depending arm 23 to which is pivotally connected one arm of a bell crank 24, said bell cranks being pivotally mounted, as at 25, and being connected, as by means of rods 26, to oppositely extending arms of bell cranks 27 which are mounted at one side of the track and are connected together and also connected to the bell crank 18 by rods 28 so that all of the bell cranks are caused to move in unison. It will be observed by reference to the draw ings, particularly with reference to Figs. 1 and 2, that since the rods 26 of the bell cranks 24 are connected to oppositely extending arms of the bell cranks 27, said rods, together with their bell cranks 24, are moved simulta neously in reverse directions so that when one pair of toggle bars are depressed at one side of the track to move the switch points in one direction, the toggle bars at the other side of the track Will be raised in position to be operated by a train passing in the opposite direction, and hence the said toggle bars and other connections serve to automatically operate the switch points as a train moving in either direction approaches the switch.

In Figs. 5 and 6 I show train-operated means for thus depressing appropriate pairs of toggle bars to automatically operate the switch points. A truck 29 of a locomotive, car or other element of a train is provided with a rocking bar 30 which is pivotally mounted, as at 31, and has depending arms 32, 33 at its ends, each provided at its lower end with a fork in which is mounted a tappet wheel 34. The said rocking bar is connected by a link 35 to a'bell crank 36 to which is attached an operating rod 37 which may lead to the cab of the locomotive so that it may be operated by the engineer or fireman to cause'either end of the rocking bar to be depressed and hence cause one of the tappet wheels carried by the said rocking bar to engage and depress one pair of the toggle bars, as the train approaches a switch to cause such depressed toggle bars to move the switch points in the required direction.

ment, and rods connecting said bell crank to said operating oscillating element, connections between said rods and such elements being at opposite sides of the pivot of said element.

2. In combination with fixed rails, movable switch points, a bar connecting such switch points together, spring operated means secured to said bar and movable with said bar and switch points to lock the latter to one of the fixed rails when said switch points are set in either position, means to actuate the switch points, and operating means carried by said bar and for the said spring locking means actuated by the switch point actuating means, for the purpose set forth. I

3. In combination with movable switch points and fixed rails, a bar connecting such switch points together, spring catches carried by the bar to engage the bases of said fixed rails according to the direction of movement of said bar, operating devices for the said spring catches and an operating rod connected to the said operating devices and also to the said bars, said operating rod having lost motion with referenceto said bar.

In testimony whereof, I affix my signature in presence of two witnesses.
